Abstract (en)
[PROBLEMS] To provide an epoxy resin giving a cured object having high heat resistance, which is improved in impact resistance and moisture resistance as compared with conventional high-heat-resistance epoxy resins. [MEANS FOR SOLVING PROBLEMS] The epoxy resin is obtained by glycidylating one or more phenol compounds comprising 95% or more 1,1,2,2-tetrakis (hydroxyphenyl) ethane, and is characterized in that in an examination by gel permeation chromatography, the epoxy resin has a tetranucleus-form content of 50 to 90% by area and an octanucleus-form content of at least 5% by area and has a total chlorine content of 5,000 ppm or smaller.
